For those that need a refresher Rising Storm 2: Vietnam is essentially Battlefield-like online shooter, right down to huge open maps, 64 players, explosives, and vehicles.

The Australians were a major player on the anti-Communist side of the war for 10 years, between 1962 and 1972, along with supporting elements from New Zealand. They will be fully represented in this free update, with new uniforms, unique customization options and specially recorded voice-over.
